### Font Sizes

If you'd like to customize your values for font sizes, use the `theme.fontSizes` section of your theme.

```diffjs
  // theme.js
  export const theme = {
    fontSizes: {
-     'xs': '.75rem',
-     'sm': '.875rem',
+     'tiny': '.875rem',
      'base': '1rem',
      'lg': '1.125rem',
      'xl': '1.25rem',
      '2xl': '1.5rem',
-     '3xl': '1.875rem',
-     '4xl': '2.25rem',
      '5xl': '3rem',
      '6xl': '4rem',
+     '7xl': '5rem',
    },
  }
```

If you don't want to customize it, a set of `fontSizes` is already defined in default theme:

```js
const defaultTheme = {
  // ...
  fontSizes: {
    xs: '0.75rem',
    sm: '0.875rem',
    base: '1rem',
    lg: '1.125rem',
    xl: '1.25rem',
    '2xl': '1.5rem',
    '3xl': '1.875rem',
    '4xl': '2.25rem',
    '5xl': '3rem',
    '6xl': '3.75rem',
    '7xl': '4.5rem',
    '8xl': '6rem',
    '9xl': '8rem',
  },
}
```
